Why didn't anyone tell me oral was so good😍

Today my gf went down on me and oh. My. God. Yall it was amazing!! Shes seriously magic and made me cum so much. I tried doing the same for her n I did a bit but I felt a bit unsure so I started fingering her bc I have more experience with that but I wanna try to please her with my mouth a bit more. Do yall have any recommendations for positions or techniques so maybe I know what I'm doing next time? Or maybe I should just learn from experience
